Polycraft Target Foam is a two component polyurethane foam system, that when mixed gives a medium density soft, elastomeric foam. The foam is self skinning, durable and has excellent physical properties. Typical free rise density is between 140 - 180 kgm, however the foam can be over packed in the mould to give higher densities of up to 500 kgm. The final hardness of the foam can be adjusted by small adjustments to the mixing ratio. The product is ideal for applications requiring a tough, durable foam, such as the manufacture of archery targets

Variable Foam,

Different mix ratios can be added

Soft, Medium or Hard foam can be achieved

Self-Skinning, Durable, Easily Pigmented, Rapid Demould

Polycraft Target Foam can be used at 100:30 by weight for soft foam, 100:33 by weight for medium foam and 100:36 by weight for a hard foam, different ratios will produce different foam hardness.

For bulk castings using Medium and Hard Target Foam, shrinkage of the cured product may be observed.

For best results ensure resins and moulds are at temperature above 25°C before using, using at colder temperatures will effect cured characteristics and may inhibit cure. Ensure moulds are free from dust and other contaminants. Always perform small test before pouring large amounts to ensure suitability. The user must first thoroughly test the foam before going into production. Excessive usage of isocyanate can cause hardening of soft foams over time and may even cause excessive contraction of the moulding. Polycraft foams are moisture sensitive, keep containers closed when not in use. When stored correctly unopened product has a shelf life of 6 months from purchase.
